web-config – MVC 4网站加载显示HTTP错误500.19

我基于Internet应用程序模板创建了一个新的ASP.NET MVC 4应用程序,我可以成功运行它并从VS 2012 Express中验证用户身份.

然后将其发布到wwwroot中的文件夹,然后在IIS 7.5管理器中创建指向该文件夹的虚拟目录,并使用单独的4.0集成池将其转换为应用程序.

当我尝试从IIS管理器中浏览应用程序时,我收到下一个错误：

http错误500.19 – 内部服务器错误,
无法访问请求的页面,因为页面的相关配置数据无效.

配置错误：无法添加“add”类型的重复集合条目,并将唯一键属性“name”设置为“ExtensionlessUrlHandler-Integrated-4.0”

配置来源：

56:       <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,deletE,PATCH,OPTIONS" type="System.Web.Handlers.TransferrequestHandler" preCondition="integratedMode,runtimeVersionv4.0"/>
57:       <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferrequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />   
58:     </handlers>

searched here,我找到了相应的答案：

决议1

从ApplicationHost.config文件或Web.config文件中删除格式错误的XML元素.

我的web.config文件如下：

<?xml version="1.0"?>
    <configuration>
      <configSections>

由于我是MVC 4中技术娴熟的开发人员,我会问是否有人可以在上面的文件中找出格式错误的xml元素.

<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferrequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,runtimeVersionv4.0" />

<add name="ExtensionlessUrlHandler-Integrated-4.0a" path="*." verb="*" type="System.Web.Handlers.TransferrequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0b" path="*." verb="GET,runtimeVersionv4.0" />
